IPC: B66F9/24
Filed: 2001-08-31
Abstract: PROBLEM TO BE SOLVED: To allow an operator to get off from a driving operation mount without any aid of another operator even in an emergency when the operation of a raising/lowering operation device is impossible. SOLUTION: When a traveling/hydraulic control unit 13 detects disconnection of a signal wire 30, the unit 13 stops the traveling of a vehicle and the raising/ lowering of the driving operation mount 2 and transmits a disconnection signal to a steering control device 26. The steering control device 26 receiving the disconnection signal stops the driving control of a steering motor 22 and waits for a signal inputted from a steering sensor 25 and so on. When a steering wheel 6 is rotated in this state, the operation is signalized by the steering sensor 25 and the signal is transmitted to the steering control device 26. The steering control device 26 transmits the operation signal to the traveling/hydraulic control unit 13 and the traveling/hydraulic control unit 13 lowers the driving operation mount, when the operator operates the steering wheel 6 in the left direction.
